SHEET-DELIVERY.

SPECIFICATION forming part of Letters Patent No. 77 5,319, datedNovember 22, 1904. Application filed March 1, 1904. Serial No. 195,974.(No model.)

To (1]7- whom it rnrty concern.-

Be it known that l, ARTHUR K. TAYLOR, a citizen of the United States ofAmerica, and a resident of 2120 Chelsea Terrace, \Valbrook, Maryland,have invented certain new and useful Improvements in Sheet-Deliveries,of which the following is a specification.

My invention relates to certain new and useful improvements insheet-deliveries for use in connection with cylinder printing-presses.

The object of my invention is to produce a back delivery which willdeliver the sheet printed side up.

in the ordinary form of back delivery the sheets are delivered with thefreshly-printed side down, and consequently they are more liable tooffset onto the sheet upon which they rest than would be the case ifthey were delivered printed side up.

In orderto obviate the diflieulty of delivering the sheets printed sidedown, the front delivery has been used. The objection to this form ofdelivery is, however, that a press has to be especially designed to usesuch a delivery, whereas with my form of device the delivery may beattached to an ordinary cylinder-press.

1n the drawings accompanying this application 1 have shown my deliveryattached to an ordinary form of stop-cylinder press. I desire to have itunderstood, however, that I am not to be limited to the use of mydelivery with such a press, as itis adapted for general use and in theform shown may be used in connection with any form of cylinder-pressdesired.

Referring to the drawings, wherein the same part is designated by thesame reference-numeral wherever it occurs, Figure 1 is side elevation ofa press provided with my invention in its preferred form, the pressbeing shown in dotted lines to more clearly show the features of myinvention. Fig. 2 is a top plan view of Fig. 1. Fig. 3 is a sideelevation of the grippers and the holding-cam therefor. Fig. A is a topplan View of Fig. 3. Figs. 5,

6, 7, 8, and 9 are diagrammatic views showing the operation of mydelivery.

1 designates the frame of a stop-cylinder press, 2 the feed-board, and 3the impression-cylinder. 4 designates the shaft on which theimpression-cylinder is mounted, and 5 is the driving-gear carried by theshaft 4 at one end of the impression-cylinder. These parts, as shown.are all of the ordinary form of stopcylinder press and will not befurther described.

6 isashaftmounted in bearings in the frame 1 and carries inside theframe the gear 7, meshing with the gear 5.

8 is a shaft similar to the shaft mounted on the other side of the framefrom the shaft 6 and provided with the gear 9.

10 is a shaft mounted in bearings on the frame of the machine, and theshaft carries a pairof gears 11, which mesh with the gears '7 and 9,whereby the gear 9 is driven in unison with the gear 7.

Loosely mounted on the shafts 6 and 8 inside the gears and 9 are thearms 50, and connecting the free endsof these arms is a rod 51, uponwhich the grippers 52 are mounted. Extending between the arms is a bar12, which forms a stationary jaw of the gripper. At each end of the rod51 there is an upwardly-projecting arm 13, to each of which arms 13there is connected a rod 1A1, passing through lugs 15 15, located uponthe sides of the bars 9 9. The inner end of each of the rods 1% 14:carries a cam-roller 16, adapted to be operated by the cams 17 17 on thestubshafts 6 6. 18 is a spring surrounding the rod 14 and pressing thecamrollers 16 16 against the earns 23 23. By this construction it willbe seen that when the high partof the cam 17 is under the roller 16 thegrippers will be closed, and when the low part of the cam passes belowthe roller the grippers will be opened by means of the spring 18.

19 19 are arms, one end of each of which is pivoted to the frame at 20and the other end of which is pivoted to each of the arms 9 at 21.Between its ends these arms carry a camroller 22, which is adapted to beoperated by the cam 23, mounted upon each of the shafts 6. By thisconstruction it will be seen that the cam 17 is adapted to raise andlower the grippers from the position indicated diagrammatically in Fig.9 to the position shown in Fig. 5.

Mounted in suitable bearings 24 in the frame v of the machine is aspring apron-roller 25, and.

secured to this apron-roller is an apron 26. The spring of the roller isarranged so thatit will maintain a constant pull upon the apron. Theapron-roller is mounted in front of and just above the position of thegrippers when 1 they are in their lower or sheet-taking position, asindicated in Fig. 1.

27 is a shaft, which receives motion from a suitable source of power,and mounted on each end of it is a cam 28,which preferably is of theform shown in Fig. 1. i

29 29 are rods, which at their lower ends are divided to straddle theshaft 27 and guide the rods, and each of the rods is provided with acam-roller 30, running in the groove of one of the cams 28, whereby therods are reciprocated. Each rod carries at its upper end a rack 31,meshing with one of the pair of pinions 32, which are mounted on theends of the shaft 33, and this shaft carries at each end, just withinthe pinions 32, two gears 34 34.

35 35 are two rack-bars, one on each side of the machine, engaging thegears 34 34. The front ends of these rack-bars are connected together bymeans of a bar 36, and to this rod the free end of the apron isconnected.

Mounted on each end of the shaft 27, outside the cam 28, is a cam 37,which engages the lower ends of the rods 38, which are mounted insuitable lugs 39 on the frame of the machine. The free ends of the rodsare connected together by the rod 40, extending across the machine fromone rod 38 to the other.

41 41 are a pair of rollers driven from the shaft 27 by the pulley 42thereon and the belt 43. Passing over these rollers is a receivingweb44, which receives the sheets as they are delivered by the apron andcarries them away in any desired manner.

While I have described my sheet-delivering device as an apron, it is tobe understood that instead of an apron tapes may be used or any othersuitable receiving device.

In the operation of my machine the gripper-carrying arms 50 are so timedas to be brought to their lowest position (shown in Fig. 1) shortlybefore the impression-cylinder stops, in which position the grippers ofmy device will be in the path of the grippers of the impression-cylinderand in' position to receive the sheet from the latter, which normallyrelease the sheet shortly before the cylinder comes to rest. During thelatter part of the revolution of the cylinder the cams 17 17 firstoperate to close the grippers onto the sheet, and immediately thereafterthe cams 23 23 operate to lift the gripper-carrying arms 50 by means ofthe arms 19 and raise the grippers, carrying the sheet to the positionshown in Fig. 5, in which position the grippers are i above the rod 36,to which the front end of the apron is attached. The sheet now hangs inthe position shown in Fig. 5. The cam 28 is so timed that it wlll nowbegm to move the bar 29 up. which through the rack 31, and gears 32 and34 will reciprocate the bars 35, drawing the apron from the positionshown in Fig. 5 to the position shown in Fig. 6. The bar 36, passingunder the sheet, will raise the same and cause the sheet to lie on topof the apron. As soon as the rack-bars have completed their movement,drawing the bar 36 to the position shown in Fig. 6, theimpression-cylinder will start on its neXt revolution, and this willoperate to open the jaws of the gripper and let go the sheet. The cam 37now operates to raise the rod 38 and through the rod the bar 40, so thatthe bar moves into the position shown in Fig. 6 and lifts up the backend of the curtain. The continued rotation of the cam 38 causes the bar29 to move back, thus moving the rack-bars towardtheimpression-cylinder. Because the bar 40 has been moved above the bar36 this will loop the apron over the bar 40 and further draw the apronoff from the springroller 25, and thus advance the sheet until itsforward end drops down upon the web 44 or any other similar receivingdevice. The movement of the apron when advanced to its limit should freeitself of the sheet and deliver it onto the conveyer-web 44. The cams 28now reciprocate the bars 39 in the opposite direction, causing the bars35 to move backward, and thus move the bar 36 back to the position shownin Fig. 8. The cam 37 now allows the bar 40 to drop back to its normalposition, and the cam 28 operates to move the bar 36. to its normalposition, when the parts will come to the position shown in Fig. 9 andbe ready to receive another sheet and will have completed their cycle ofoperations. As the sheet is raised by the lifting-arms the apron passesunder the sheet and turns the printed side up, in which position it ismaintained until it is deposited upon the receiving device.

WVhile I have described what I believe to be the preferred form of myinvention, I desire to have it understood that many changes andmodifications may be made therein without departing from the scope ofsame.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
